ALRM SEQ
The Alarm Sequence setting establishes how the sequence number for alarms is generated. Set
this option to
all
if you want any alarm generated by the system to be assigned a sequence
number. Or, set this field to
report
if you want only the alarms set to
report
to have sequence
numbers.
ACO
The Alarm Cutoff (ACO) option reports a status to you based on the
latch
(condition held) or
cur
(current condition) setting.
5.3.2 Printing Alarms Remotely
Integrated access systems are typically placed in unattended locations (equipment closets,
etc.). If no one is present to detect alarms that might occur, a system administrator has no way
of knowing whether or not the system is working properly.
The solution to this network management problem is the Print Alarm feature. Each system unit
can be programmed to call a predetermined telephone number at specific intervals and report
the presence of selected system alarms. Choose alarms to print remotely by selecting the
Report
option in the alarm filters.
You can use either an external modem or the internal modem (2.4 kbps) on many of the
Interface cards to send system alarms to a remote logging device, such as a printer or personal
computer. If using the internal modem, the remote device should be connected to a V.22bis 2.4
kbps asynchronous modem set to auto-answer mode, eight data bits, one stop bit, and no
parity. When the modem connected to the remote logging device answers, the system sends
the alarm messages as a string of ASCII characters formatted with carriage returns and line
feeds, then terminates the call. More information on this process can be found later in this
chapter.
A network administrator can also call the phone number associated with the system modem
and initiate a two-way, interactive VT-100 session with the system to determine the nature of
the problem and dispatch technicians if necessary.
Another Network Management solution is the TCP/IP feature discussed later in this chapter.
Note that
if the TCP/IP network management system is active, the Print Alarm feature
will not operate.
Using the TCP/IP feature automatically converts alarm messages into SNMP traps for
forwarding to downstream NMS equipment.
